Well, I tried mounting the CD and typing the above move command, and I
did get the man pages and info explorer stuff back. However, I still
don't think all of it is on the CD. The files from the install tapes
add up this way (the directory is /usr/lpp/info/En_US):
2436 ./educ
56 ./exer
32048 ./prog
2644 ./aixmin
2568 ./nav
28404 ./aix
68160 .
With the CD mounted, the same directory looks like this:
8041 ./aix
615 ./educ
11 ./exer
587 ./fortran
5498 ./graph
2698 ./hardware
643 ./nav
774 ./pascal
10830 ./prog
29697 .
It looks like I'm missing things with the CD.

That did help. The dump worked with the lower density device. Thanks!
